Hi,
I had a question for the screeners and the more experienced photographers out there. Is 16:9 an acceptable aspect ratio for aviation photography or not? I have a broad side shot of one of my helos which is not very level and will not fit in the usual 3:2 that I go for.

Also wanted to mention that after a long break from photography and the site I'm back for the summer months, and looking forward to contribute more to the site.

16:9 (or 4:3) is a widely accepted aspect ratio.
If your picture is not level, you probable get some 'corners' after leveling. After cropping the aircraft up to its 16:3 ratio you may have these corners still visible.
You may try to correct this by marking the sky (or flight line, where-ever these corners are) and try the option 'transform'. By stretching or warping the selection you will be able to correct the corners.
If you are not quite sure, you may upload the picture as it is (in resolution 2000+). We can give it a try than and come up with a solution.

Hi,
16:9 and 4:3 are not the same thing. 4:3 and 16:12 are the same ratio. 4:3 is more square looking while 16:9 is your standard wide screen aspect ratio. I've never seen 16:9 be used in anything other than HD video that's why I asked.

The picture above is just an example I used for the two different aspect ratios. The second one being the questionable one as far as aviation photos go.

The helo concerned is this following one, as you can see it needs quite a bit of CW rotation and by doing so and cropping at 3:2 or 4:3 you end up cutting major parts of the aircraft. The "wide screen" crop would be the only one that saves it but again I'm uncertain about its acceptance.
